作業二：

我自己寫的：

#!/usr/bin/env python
#-*-coding=utf-8 -*-
#AUTHOR:duwentao

username = ['duwentao','liuxiaohui']  #存儲用戶名
password = ['123456','456789']      #存儲對應的密碼
locking = []        #用於鎖定
n = 0       #計算輸入了幾次
while True:
    UserName = input('請輸入用戶名：')
    if UserName not in locking:
        if UserName in username:
            PassWord = input('請輸入密碼：')
            if PassWord == password[username.index(UserName)]:
                print ('登錄成功')
                exit()
            else:
                n = n+1
                if n == 3:
                    locking.append(UserName)
                print ('用戶名或者密碼錯誤，登錄失敗')
        else:
            PassWord = input('請輸入密碼：')
            print ("用戶名或者密碼錯誤，登錄失敗")
    else:
        print ("該用戶已被鎖定")

運行結果：
